FURNACE.

SPECIFIGATIONforming part of Letters Patent No. 707,103, datecl'August 19, 1902.

Application filed August 2, 1-901.

To all whom it mag concern Be it known that I, ROBERT HALLEY, a citi zen of the United States, residing in Chicago,

My invention is concerned primarily with.

a rotatable furnace in which a plurality of objects, such as tires, can be heated simultaneously, and which consists of a central stationary burner which directs a flame into a plurality of radialapertures and each aperture is adapted to receive a tire, so that the operator can take out one tire that has been heated sufficiently and replace it by a fresh one. The furnace is then rotated to bring another tire to the operator, which is removedand replaced by a fresh tire, the construction being such that when the'furnace has made a complete rotation the tire which was placed in it at the beginning of the rotation will be sufficiently heated at the end of the rotation so that it is ready to be welded or otherwise manipulated.

Refering to the accompanying sheets of drawings, in which the same reference characters represent identical parts-in all the figures, Figure 1 is a plan view of the furnace with the burner removed. Fig. 2 is a vertical section thereof on the line A .A of Fig. 1. Fig. 3 is a plan view of one of the angle-irons forming the sides of the furnace. Fig. 4. is a plan view of the machine with all the mechanism above the bottom plate removed, and Fig. 5 is a central section through the burner on an enlarged scale.

The furnace is provided with the heavy,

- preferably circular, base-piece 6, which has plate 11-of the furnace'is preferably of the shapeshown in Fig. 4 and has the sleeve 12 projecting downward from the center thereof tire is in place.

Serial No. 70,588. oto'moaei.)

the annular groove or channel 13, which is opposed to the channellO, and the antifriction-balls 14 are placed in said channels, so as to insure the easy rotation of the furnace upon the base-piece. I preferably place the sleeve "15 on the outside of the reduced portions of the sleeves 7 and 12 in order to pro-- vent any dust getting into the hearing. The

bottom plate 11 may be reinforced by the flanges 16, as shown in Fig. 2. The sides of the furnace are formed by the four angle-irons 17 ,which have the ears 18 thereon. The top of the furnace is made up of the four iron plates 19 of the shape shown, and'these are also provided with the ears'20. The bottom plate 11 is provided with the ears 21, the ears 18, 20, and

21 being in alinement with each other, so that by passing the bolts 22 through said ears the bottom plate, sides, and the top-platesmay be securelyclampedtogether. The furnace-cavity thus formed is lined with the fire-brick 23 in the customary manner, and it will be seen Another fire-brick 28 is preferably placed on' the brick 27 and the upper horizontal portion of the support 25 after the The fire-bricks forming the lining for the bottom of the furnace are preferably cut away, as shown at 29, so as to permit the flame passing down underneath the edge of the tire and up against the'brick 27, from which it is reflectedtback, against the "and fitting over the bearing 9. The-bottom of the sleeve 12 is preferably provided with space to permit the entranceof the tire 27 to the opening.

tire. Similarly the flame passesover the top the under sideof the'bottom-plate 11 or any other convenient. portion of the furnace, and

to the upturned outer ends 31 of these angleirons I bolt or otherwise secure the iron ring 32, upon which the tire rests. As seen in Fig. 2, the burner 33 is centrally disposed in the top plates and directs the flame downward into the furnace, when it is deflected radially out to the apertures 24.

The details of the burner 33 are best shown in Fig. 5, and in Fig. 2 it will be seen that I lead a pipe 34 for compressed air to the top of the burner, a pipe 35 for oil to the side of the burner, and a large pipe 36 for a blast of air from the blower to the side of the main portion of the burner. This main portion consists of a cylindrical shell 37, having at one side thereof the cylindrical offset 38 with the large aperture 39 therein. A collar 40 is bolted thereto and has a flange 41, upon which the end of the pipe 36 is placed, resting against the shoulder 42. An ordinary slidevalve 43 is placed in the channel between the offset 38 and the collar 40, which can be opened or closed, as may be desired, to admit or shut off the air-blast from the burner. A block 44, which has the preferably circular passage 45 therethrough, has its lower end '46, which is square or some similar angular shape in cross-section, taking into a similarly-shaped aperture 47 in the top of the furnace, so that as the furnace rotates the block 44 will rotate'with it. The block 44 has a flange 48 formed thereon about midway its height, which rests on the top of the furnace when the burner is in position. Above the flange 48 the block is reduced in diameter, as seen at 49, and is preferably circular in crosssection, so that it is free to rotate in the correspondingly-shaped recess 50, formed in the lower part of the block 37, which is preferably provided with a flange 51, which rests upon the flange 48. With this construction of the parts it will be seen that the burner remains stationary and in the axis of the rotating furnace. The burner proper consists of the tube 52, which has a screwthreaded portion 53, which is screwed into an aperture 54, formed in the top of the block 37. The end of the pipe 34 is screwed into a recess in the upper end of the tube 52 and delivers air into the channel 55,which extends through the length of the burner-tube. Near its upper end the burner-tube has a cylindrical enlargement 56, through which extends transversely the plug 57, which has an L shaped channel 58 therein, one end opening to the outside and having the oil-pipe 35 screwed therein,while the other end opens on theinterior of the tube 52 downwardly and has the oil-pipe extension 59 screwed or otherwise secured therein, so that the oil from the tube 35 passes down and is discharged from the nozzle 60. For convenience of assembling the parts I preferably make the nozzle 61 of the burner, which surrounds the nozzle of the oil-pipe extension, removable, and, as seen in Fig. 5, its largest interior diameter is at its upper end, which fits over the reduced end 62 of the burner-tube 52, where it is preferably secured in place by a set-screw 63. The lower end of the channel through the nozzle 61 is preferably reduced by a taper toward the bottom, so that at the end of the nozzle 61 there is only a very slight annular opening around the nozzle 60.

In the operation of the burner the oil is supplied by gravity through the oil-pipe extension 59,,and compressed air from the tube 34 passes down through the tube 52 and is discharged from the nozzle 61 and has a suction or atomizing effect on the oil to draw it from the nozzle 60 and to discharge it from the bottom of the burner, where it is ignited, the necessary air for combustion being supplied through the tube 36. To assist the compressed air in atomizing and breaking up the oil, I may employ the four or more pins 64, which are placed in the sides of the portion 46 of the block and have their sharp points extending to the center of the channel 45 in position to receive the stream of oil and break it into particles.

While I have herein shown and described a preferred form of burner to be used in connection with the rotary furnace, I do not limit myself to this specific form of burner, as I may employ some other form which is capable of producing the same results, and while I have shown and described the details of said burner I do not herein claim the same, but reserve the subject-matter thereof for my divisional application, Serial No. 81,221, filed November 5, 1901, covering the same.

While I have shown my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of some modifications, and that I do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the prior art.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1.
